Anti-bovine thyrotropin autoantibodies in patients with Hashimoto's thyroiditis, subacute thyroiditis, and systemic lupus erythematosus.

We report four cases found to have anti-bovine thyrotropin (bTSH) antibodies, two with Hashimoto's thyroiditis and the other two, each with subacute thyroiditis and systemic lupus erythematosus (SLE). The unusually high negative titers of anti-TSH receptor antibodies (Case no. 1, -43.1%; Case no. 2, -34.9%; Case no. 3, -55.2%; Case no. 4, -59.9%) led to the incidental finding of the presence of anti-bovine (bTSH) antibodies in each patient. Case no. 1 was diagnosed to have Hashimoto's thyroiditis and was treated with L-thyroxine (L-T4). With the treatment, serum free T4 (FT4)normalized with a decline in the serum TSH concentration. The other patient diagnosed to have Hashimoto's thyroiditis (Case no. 2) remained euthyroid even without supplemental thyroid hormone therapy and the serum concentrations of FT4 and TSH stayed within the normal range. The third is a case of subacute thyroiditis (Case no. 3) with a typical clinical course of the disease. She had the anti-bTSH antibodies on her first outpatient visit. Serial examination of her sera disclosed the antibody titers to be on the same range over the 28 months after the onset of the symptoms. The fourth is a patient with SLE who had been treated with steroid (alternative day therapy of 40 mg/day prednisolone). Titers of the anti-bTSH antibodies spontaneously declined to the negative level 5 months later. None of the four cases had antibodies against human TSH alpha-subunit of bovine LH and alpha-subunit of bovine FSH.(ABSTRACT TRUNCATED AT 250 WORDS)

Atypical presentation of subacute thyroiditis.

Subacute thyroiditis is extremely rare during the first decade of life. We describe a case of subacute thyroiditis in a 2 year old child whose initial clinical, sonographic, and radioisotopic features were indistinguishable from acute suppurative thyroiditis. The diagnosis was established by a raised antibody titre against adenovirus and typical increased thyroid function tests.

[High alkaline phosphatase in subacute thyroiditis].

Subacute thyroiditis may be hard to diagnose, therefore patients are sometimes misdiagnosed and subjected to unnecessary work-up. We report a 37-year-old man with subacute thyroiditis and a high concentration of serum alkaline phosphatase. After aspirin treatment there was clinical improvement and decrease in rapid ESR, and in high serum thyroxin and alkaline phosphatase. The increased alkaline phosphatase, seen in as many as 50% of patients, is of hepatic origin, and is not caused by high serum thyroxin. Awareness of this relationship may help in diagnosis and may prevent unnecessary diagnostic procedures, which may be invasive.

Incessant ventricular tachycardia due to subacute thyroiditis.

Subacute thyroiditis is a possibly viral, inflammatory thyroid disorder which can cause thyrotoxicosis. Ventricular arrhythmias are uncommon in thyrotoxicosis and usually occur only in those with marked heart failure or associated cardiac disease. In this case, we present a 52-year-old woman having incessant ventricular tachycardia due to subacute thyroiditis without underlying cardiac disease.

[Painful lymphocytic subacute thyroiditis].

Subacute granulomatous thyroiditis (SGT) and subacute lymphocytic thyroiditis (SLT) present a similar evolution during the first year, however, posteriorly, except on rare occasions, SGT maintains normofunction while SLT may present relapse with persistent goiter or permanent hypothyroidism requiring periodic follow up. The presence of spontaneous pain and very elevated VSG have been described accompanying SGT but not SLT histologically proven to be used for differentiating these entities. Two cases with clinical criteria and cytological diagnosis of SLT consulted for spontaneous thyroid pain are presented. VSG greater than 50 mm/1st hour was suggestive of SGT. The importance of cytology for the correct management of subacute thyroiditis is emphasized.

CT and MR imaging findings associated with subacute thyroiditis.

Subacute granulomatous thyroiditis is an uncommon disease that occurs most often in women in their second to fifth decades of life. This disease usually presents with thyroid tenderness, a low grade fever, and occasional dysphagia. The disease resolves spontaneously, usually without thyroid function abnormalities. We herein present the CT and MR imaging findings of two cases of subacute granulomatous thyroiditis.

[Lymphocyte subpopulations and the soluble interleukin-2 receptor in Hashimoto's thyroiditis and subacute thyroiditis].

There are no univocal experimental data in literature about T cell clone alterations in the peripheral blood during Hashimoto's thyroiditis (TH), autoimmune disease, and during subacute thyroiditis (TSA), an inflammatory thyroid lesion with possibility of "self-perpetuation". The object of our research was to examine the T cell clones, soluble fraction of interleukin 2 receptor and HLA-DR modifications in patients with TH and TSA compared with healthy population. Our results show significant increase of sIL-2r in the TSA compared with normal subjects and with patients TH, where on the contrary, a constant increase of HLA-DR was observed.

TSH receptor antibody-associated thyroid dysfunction following subacute thyroiditis.

OBJECTIVE: Autoimmunity plays an important role in the development of thyrotrophin (TSH) receptor antibodies and the pathogenesis of Graves' disease and Hashimoto's thyroiditis. On the other hand, subacute thyroiditis is a self-limited inflammatory disease of presumed viral aetiology. The aim of this study was to examine whether subacute thyroiditis triggers TSH receptor antibody-associated thyroid disorders. PATIENTS: We reviewed 1,697 patients with subacute thyroiditis seen between 1985 and 1995. DESIGN AND MEASUREMENTS: We measured antibodies which inhibit the TSH binding to the TSH receptor (TBIAb), thyroid stimulating antibodies (TSAb) and antibodies that block TSH action (TBAb). Other thyroid autoantibodies were also determined. RESULTS: TBIAb became positive in 38 patients following subacute thyroiditis. Thyroid function after the development of TBIAb appeared to be influenced by the bioactivity of the antibody. Hyperthyroidism developed in the presence of TSAb, and so did hypothyroidism in the presence of TBAb, although 21 patients did not have thyroid dysfunction despite high titres of TBIAb. Fifteen out of 17 patients recovered from hyperthyroidism or hypothyroidism after the disappearance of TBIAb sometimes even without medication. TBIAb-positive patients had a high incidence of a family history of thyroid disease and positive anti-thyroid microsomal antibodies. An ophthalmopathy similar to Graves' disease was also observed in 3 patients. CONCLUSIONS: Subacute thyroiditis may trigger autoreactive B cells to produce TSH receptor antibodies, resulting in TSH receptor antibody-associated thyroid dysfunction in some patients.

Thyroid hemiagenesis with subacute thyroiditis.

A 58-year-old woman with thyroid hemiagenesis associated with subacute thyroiditis is described. Physical examinations revealed a firm nodule with spontaneous pain and tenderness in the left thyroid lobe. A serum thyroid hormone levels were elevated and thyroid scintiscan with 99mTc pertechnetate showed an extremely low uptake, we made a diagnosis of subacute thyroiditis. A 201Tl thyroid scan demonstrated an enlarged left lobe and absence of the right lobe. Ultrasonography of the thyroid gland revealed an enlarged left lobe occupied mostly with a hypoechoic region. An incidental finding was absence of the right lobe. Two months later thyroid function returned to normal. A follow-up thyroid scintiscan revealed a normal left lobe but absent right lobe. The diagnosis of hemiagenesis was confirmed by CT scan. This appears to be the first case report of thyroid hemiagenesis associated with subacute thyroiditis.

Persistent thyroid autoimmunity after subacute thyroiditis.

Subacute (de Quervain's) thyroiditis (SAT) is accompanied by temporary abnormalities in thyroid function and, in a minority of patients, by transient thyroglobulin and thyroid microsome autoantibody formation. In this report we have examined the sera of patients with SAT for the presence of multiple thyroid autoantibodies using qualitative immunoblotting (Western blotting). For this purpose we used a crude thyroid extract (2,000 g supernatant) as a source of antigen, in order to identify antibodies reacting with a wide range of potential autoantibodies. Eight of the 9 patients tested had autoantibodies which reacted with between 2-18 antigenic determinants (molecular weights 177-10 kd) present in the thyroid antigen preparation. None of the sera reacted with thyroglobulin or thyroid microsomes. The majority of these autoantibodies were directed against antigens which were absent from liver membrane preparations. Furthermore there was no diminution in the levels of these autoantibodies over a period of up to 39 months after the onset of SAT. The prolonged presence of these novel thyroid autoantibodies may explain the recent findings of subtle thyroid defects, such as altered gland iodine content, long after apparent clinical resolution of SAT. The accumulated evidence for a viral aetiology in this condition suggests that these sequelae may be due to a virally-induced autoimmune response.

T lymphocyte subsets in autoimmune thyroid diseases and subacute thyroiditis detected with monoclonal antibodies.

Peripheral T lymphocyte subsets were analysed with monoclonal antibodies, by highly standardized fluorescence-activated cell sorter analysis instead of manual counting by the indirect immunofluorescence method, in autoimmune thyroid diseases and subacute thyroiditis. Total lymphocyte counts were increased in patients with thyrotoxic Graves' disease and subacute thyroiditis. The percentage of total T (Leu 1) cells was significantly lower in patients with thyrotoxic Graves' disease and Hashimoto's disease with destructive thyrotoxicosis than in normal subjects. No significant changes were observed in the percentages of suppressor-cytotoxic T (Leu 2a) cells or helper-inducer T (Leu 3a) cells or in the Leu 3a-Leu 2a ratio in different groups of patients. There were no correlations between the percentages of E rosette-forming cells and Leu 1 cells and between the percentages of T gamma cells and Leu 2a cells in normal subjects and patients. The peak position of fluorescence intensity of Leu 2a cells showed a significant sex difference even in normal controls. The most important finding was a significant decrease in the peak position of Leu 2a cells in patients with thyrotoxic Graves' disease and with hypothyroid or thyrotoxic Hashimoto's disease. These findings indicate the significant association of qualitative, but not quantitative, abnormality of suppressor-cytotoxic T (Leu 2a) cells with thyroid dysfunction in autoimmune thyroid diseases.

Thyroid echography of subacute thyroiditis.

Ultrasound was used to study 10 patients with subacute thyroiditis. With gray-scale technique, a "washed-out" appearance was seen during the active phase of the active phase of the illness. Clinical migration of the inflammation was accompanied by migration of the sonographic abnormality. Ultrasound can be especially helpful in the diagnosis of unilateral subacute thyroiditis and the differentiation of true cysts from hemorrhagic degeneration of goiter.

Familial occurrence of subacute thyroiditis.

Although subacute thyroiditis (de Quervain's thyroiditis) is presumed to be caused by a viral infection, only 2 familial occurrences of subacute thyroiditis have been reported in the literature. Typical and severe subacute thyroiditis was diagnosed in an older sister who was hospitalized for 8 days. During this period her younger sister nursed her. Three weeks after, the same clinical picture occurred in the younger sister. We postulate that subacute thyroiditis might occur by transmission of possible viral infection in genetically predisposed individuals.

Allele 2 of interleukin-1 receptor antagonist gene increases the risk of thyroid peroxidase antibodies in subacute thyroiditis.

Subacute granulomatous thyroiditis (SAT) is a self-limiting systemic inflammatory disorder with possible transient expression of thyroid antibodies. Persistent hypothyroidism is uncommon. The interleukin-1 receptor antagonist IL-1ra is an inhibitor of IL-1 activity and allele 2 of the IL-1ra gene is associated with inflammatory diseases and IL-1ra production. Forty-eight subjects with SAT were investigated. Polymorphisms of IL-1ra, IL-1beta-511 and TNFalpha genes were studied with respect to thyroid peroxidase antibodies (TPOab), thyroglobulin antibodies, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Serum IL-1ra levels were measured. An increased allelic frequency (43% vs 22%, p=0.039) and carriage rate (79% vs 41%, p=0.018) for IL-1ra allele 2 were observed with expression of TPOab in 14 (29.2%) subjects compared with those with negative findings. The carriage rate for both IL-1ra allele 2 and IL-1beta-511 allele 2 was also increased with TPOab expression (71% vs 27%, p=0.004, respectively). No difference in allele frequency or carriage rate was found compared with healthy controls. Serum IL-1ra levels correlated with S-CRP (r=0.41, p=0.004) and ESR (r=0.34, p=0.016), but the association with genes or thyroid antibodies was statistically insignificant. S-CRP levels and ESR were lower and negatively correlated with expression of TPOab (r=-0.27, p=0.046 and r=-0.32, p=0.017). This study describes the multiplicity of the mechanisms responsible for the severity of the acute-phase response during the course of SAT. IL-1ra may have a significant anti-inflammatory role in SAT. Presence of IL-1ra allele 2 increases the risk of developing TPOab.
